The provided pie charts depict the data on waste removal across different categories in a particular nation in the years 1960 and 2011.
Overall, it is evident that there was an upward trend in the ratio of plastic, wood, and food waste, whereas the demolition of paper, textile, and other misuse types decreased. Furthermore, the disposal of metal, glass, and green waste remained relatively stable between the two years.
In 1960, approximately a quarter of the waste generated was paper, but this percentage decreased by 10% in 2011. Similarly, the disposal of textile waste experienced a slight decline of 6%, with its proportion decreasing from 17% to 11% during the same time period. Additionally, the amount of other waste disposed of in 2011 was three times lower than that in 1960.
It is evident that the proportion of plastic and food waste increased by approximately 10% in 2011 compared to the previous year. Moreover, the disposal of wood witnessed a twofold increase 51 years after 1960.
In terms of glass, metal, and green waste, the proportion of their disposal remained relatively constant over the given period. Specifically, the clearance of metal and green waste accounted for approximately 9%, while the percentage of glass waste was only 5%.
